JINNUO MOULD are good at using mould flow to find the problems at the beginning and pay attention to them in design and production process,work out the solutions.Therefore reduce risk,lower costs,shorten the construction period and improve quality.
Moldflow Examples :
1. Filling time_TV cover
2. Shrinkage_pail
3. Flow mark_40’Front cover
Hot runner with 6 valve gates, from the fill process, we
can see hesitation on the top center. And there are weld
lines on the main surface.
No.1 opened first, when the melt front reached the No.2&3gates, No.2&3opened, then the No.4&5 opened, in this mode ,the top side may filled before the under side
Although the runner is unbalanced, but we can control the time of the valve gates to decrease the influence of the unbalancedflow. And the 4 gates on the top side can give
a good compensation for shrinkage.
Most of the weld lines happened on the grid, there are no weldlines on the main appearance.
